Accompanying drawing explanation
Fig. 1 is the schema of present pre-ferred embodiments;
Fig. 2-Fig. 4 is the schematic diagram of one of the workpiece of present pre-ferred embodiments.
Embodiment
For elaboration the present invention specifically, this one embodiment of the invention is as follows:
Embodiment 1
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Fig. 1-Fig. 4, the making method of a kind of hollow watchcase or gadget, comprises step:
A, employing can make mould kind with the metal or metal alloy of hydrochloric acid or nitric acid or sulfuric acid react with;
B, employing electroforming process electroforming settled layer in mould kind;
C, in the mould kind that electroforming is complete, bore at least one relief hole;
D, the mould kind of boring put into hydrochloric acid or nitric acid or sulfuric acid, make mould kind and hydrochloric acid or nitric acid or the biochemical reaction of sulphuric acid production and be dissolved completely in hydrochloric acid or nitric acid or sulfuric acid;
E, after mould kind is dissolved, with water cleaning electroformed deposit layer.
Can have multiple with the metal or metal alloy of hydrochloric acid or nitric acid or sulfuric acid react with, as zinc alloy, sn-bi alloy, copper etc.
The concentration of hydrochloric acid or nitric acid or sulfuric acid and dissolution rate, the high dissolution rate completely of concentration is fast, and the time that the low dissolving completely of concentration spends is just long.Be preferably concentrated hydrochloric acid, concentrated nitric acid, the vitriol oil.
Relief hole is arranged on the place not affecting workpiece performance, as the side at watchcase spatial accommodation, and the not conspicuous place of gadget.
The metallic substance that electroformed deposit layer adopts be nickel, copper, gold, platinum, silver, nickel cobalt, zinc alloy one of them.But usually adopt the noble metals such as gold and silver in actual applications.
Electroformed deposit layer adopt gold platinum or silver time, before carrying out step B, in mould kind, electroplate one deck copper; First sulfuric acid dissolution is used again with after dissolving with hydrochloric acid in step D.
In steps A, the Vickers' hardness of mould kind is more than or equal to 90.In steps A, mould kind adopts die casting or gets rid of mould and carry out mach mode making.Adopt die casting or get rid of mould, mould kind can be made to have certain hardness, have certain hardness could carry out smart machining preferably, and the precision of processing can be ensured; The high workpiece of precision is produced after ensureing electroforming.
The thickness of electroformed deposit layer is 170 microns ~ 5 millimeters, to ensure the intensity of workpiece, makes the waterproof degree that watchcase can reach certain, and ornaments can resist extruding to a certain degree or collision.
In step D, hydrochloric acid or nitric acid or sulfuric acid are heated to boiling point, the acid of heating increases the speed of its dissolution of metals.
In embodiment, the workpiece made by die casting or the mode of getting rid of mould as base mateiral with zinc alloy is as mould kind, again according to the size of workpiece, scaled fine processing is carried out to mould kind, make its important fitted position and surfaceness reach requirement, also ensure that the significantly reduction of tooling cost in early stage simultaneously.Mould kind after carrying out again to the electro-coppering of mould kind, the characteristic utilizing copper close with golden physical properties thus make gold be better attached to above mould kind by electroforming.Need remove the zinc alloy of the inside and copper, after having electroplated copper and precious metal, workpiece is holed, chemical reaction is carried out by adding hydrochloric acid and being heated to boiling point, zinc alloy all with after hydrochloric acid reaction is produced zinc chloride liquid and is flowed out from workpiece lumen, and part copper also generates cupric chloride by chemical reaction and flows out from workpiece lumen; Pass through clean water again; And then making workpiece lumen extraneous copper carry out chemical reaction by adding sulfuric acid and being heated to boiling point, flow out from workpiece lumen after copper electrolytic coating complete reaction, obtaining is the workpiece of hard thousand pure golds completely; Vacuumize cleaning by clear water again, make hard pure gold (gold content is greater than 99.92%) workpiece lumen not containing acid and be in neutral state.
As in Figure 2-4, for watchcase, comprise mould kind 1, copper electrolytic coating 2 and watch case of noble metal layer 3, described mould kind 1 material is zinc alloy, and described mould kind is first obtained by die casting; Described copper electrolytic coating 2 in mould kind 1, electroplates certain thickness copper (copper thickness is generally 0.05 millimeter) obtained; Described watch case of noble metal 3 is that the certain thickness precious metal of electroforming obtained on copper electrolytic coating, and in this example, precious metal is hard thousand pure golds, and thickness is 170 microns-500 microns; Described relief hole 4(diameter 0.8 millimeter) be the hole of boring after having electroplated copper and precious metal; The zinc alloy of described composition mould kind 1 and copper electrolytic coating 2 carry out chemical reaction by adding hydrochloric acid and being heated to boiling point and melt, zinc alloy is dissolved completely in hydrochloric acid, and discharged by described relief hole 4, pass through clean water again, also containing copper electrolytic coating in watchcase after cleaned, add sulfuric acid and be heated to boiling point and carry out chemical reaction, copper is dissolved completely in sulfuric acid, discharged by relief hole 4, finally obtain described watch case of noble metal 3.
In the present embodiment, described watch case of noble metal 3 is without reinforced pipe hollow structure.
In the present embodiment, described mould kind 1 and copper electroformed layer 2 are heated to boiling point by hydrochloric acid to carry out chemical reaction, makes it be reacted into liquid, discharged by described relief hole 4.At this moment watchcase inwall also remaining copper electrolytic coating.
First use clean water watchcase 3, then add sulfuric acid and be heated to boiling point and carry out chemical reaction, finally copper reacting melt is become liquid, discharge from relief hole 4.
Embodiment two: the present embodiment structure is basic identical with embodiment one, difference is that described watchcase 3 is containing reinforced pipe 5; Described relief hole 4 is opened on reinforced pipe 5 sidewall.
Embodiment three: with zinc alloy, sn-bi alloy, copper is that the gold ornament manufacture craft of embryo material is equal to embodiment one.
The foregoing is only the embodiment of the present invention in wristwatch case, this method also can be used for other ornaments processing and manufacturing, for example pendant, bracelet, bangle, rings etc., all changes of doing according to the present patent application the scope of the claims and modification, all should belong to covering scope of the present invention.
More than show and describe ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
